| Abstract: | On analyzing the task and application environment of image tracking system on armored car,It designs the dual-processor parallel processing hardware platform,with digital signal processor(DSP) as its nucleus,which is combined with PC104 embedded computer.It also introduces in detail the design thought of realizing system bus arbitration and logical control by largescale FPGA chip.Besides,It expounds the intellectual program loading technique of DSP module and its implement method,which embodies the intellectualization level of this system.Practical system testing shows that the hardware platform can satisfy the demand for real-time,expansibility,and stability of image tracking system,and provides reliable guarantee for digitalization of armored car. |
